Abstract Higgason, K. D., and Brown, M. 2009. Local solutions to manage the effects of global climate change on a marine ecosystem: a process guide for marine resource managers. – ICES Journal of Marine Science, 66: 1640–1646. The marine environment plays an important role in controlling the amount of CO2 that remains within the earth’s atmosphere, but it has not received as much attention as the terrestrial environment regarding climate-change effects, mitigation programmes, and action plans. Potential physical effects of climate change within the marine environment, including ocean acidification, changes in winds that drive upwelling and ocean circulation patterns, increasing global sea surface temperatures, and sea level rise, can result in dramatic changes within marine and coastal ecosystems. Often, marine resource managers feel overwhelmed by the magnitude of this issue and are therefore uncertain how to begin to take action. It may seem that they do not have the time, funding, or staff to take on a challenge as large as climate change, and fail to act as a result. Using NOAA’s Gulf of the Farallones National Marine Sanctuary as a case study, this paper outlines the need to act now and presents an easy-to-use process guide, providing managers options to incorporate effectively the influences of climate change into management strategies, as well as mitigate these influences through community outreach and a reduction in workplace emissions.

The regional impact of global climate change on the ocean circulation around the Galápagos Archipelago is studied using the Hybrid Coordinate Ocean Model (HYCOM) configured for a four-level nested domain system. The modeling system is validated and calibrated using daily atmospheric forcing derived from the NCEP/NCAR reanalysis dataset from 1951 to 2007. The potential impact of future anthropogenic global warming (AGW) in the Galápagos region is examined using the calibrated HYCOM with forcing derived from the IPCC-AR4 climate model. Results show that although the oceanic variability in the entire Galápagos region is significantly affected by global climate change, the degree of such effects is inhomogeneous across the region. The upwelling region to the west of the Isabella Island shows relatively slower warming trends compared to the eastern Galápagos region. Diagnostic analysis suggests that the variability in the western Galápagos upwelling region is affected mainly by equatorial undercurrent (EUC) and Panama currents, while the central/east Galápagos is predominantly affected by both Peru and EUC currents. The inhomogeneous responses in different regions of the Galápagos Archipelago to future AGW can be explained by the incoherent changes of the various current systems in the Galápagos region as a result of global climate change.
